Appngaton med may 21,1317.Y serial No, 169,369.

To `all whom t may concern:

Be it known that 1,CHARLEs F. I SoRGnss, a citizen of lfthe UnitedStates, residing 'at '-Madison, in the/county'- of Dane, State ofv`Viisconsin ,have invented certain vnew and.

useful Improvements `in Battery Hand- `Lamps@ and 1 do hereby declarethe following to be a full, clear, and exact description yot theinvention,"such as will enable others skilled .in the 4artato which `itappertjajns to make and'use the same.

'Thezpresent invent-ion relates to battery hand lamps of a type in'which the battery is composed of a plurality of dry cells permanentlyconnected together to torni a u-nitary, rigid structure, which isserviceable as the body or handle of the device, and to one end `ofwhich a lamp fm'ay be detachably connected. Inh-and lamps of the-presentinventiomthe battery' or body portion may be discarded when the cells ofthe battery.

becomeexhausted and a lnew battery substituted. 'The initial cost of thecomplete A-e `p1ipment is low, vis compared with many hand lamps now inuse, there y1s a very considerable reduction in'weight throughelimination of the heavy fiber or metal casing in which the batteries ofsuch vdevices 'are housed.

1t is an bbjeet of the present invention to provide a batteryconstruction and a mode vof attachment for the lamp end iassociatedparts which are simple, convenient and reliable. Other objects and,adva'nt ges of the invention will be apparent from a vdescription ofcertain preferred embodiments therefof as illustrated in theaccompa'nying'r5 drawings, in whichy I device com prising a battery witha lamp attached thereto; Fig. 2 is a view in `section of the support forthe lamp;

c p Referring to thedrawing's, in which sim-i larA referencel charactersdenoter similar parts 1 throughout thekseveral views, the battery,`shown in .,Eig. '1.is composed ofthree dry cells A, B vEach vof the'cellshasa carbon `electrode 10 tipped Witha metallic: cap l1' whichAforms one terminal thereof. f j The other electrode of each cell isintlieey; form' of a zinc cup 12 which'also serves., a containervfor theelectrolytic paste., and the depolarizing materiel which constituteparts. of each cell. `The paste and materialarere--- l tained Within thelcell by the pitch seal 13. :f The foregoing details may belvaried inmany Ways. A Wrapping of impregnated, paperA or other suitable material11g-preferablyWer.y terproofed,,surrounds the zinc cup except-for asmall portionl nearithe bottom thereof. This wrapping is turned-over thetop 'of the cell and extends inward/ly 1' toward themef' tallic cap '11,as shownin Fig-et; Eachof the ce'llsoi:l the battery, except thefirstone A, hasfitted tightly upon its up-per end a metallic cap 15 whichextends inwardlyfar enough to engage the upper face ofv lterminalvv 1lto whichit preferably is soldered.y VYheirI the cells areplaced`.togetlier as rvshown-in Fig. l the zinc cup of one cell 4restsupon the a' cap l5 of an adjacent cell, but in ardentev n make a betteelectrical contact and to atp2;r tach. the cells rigidly together,solder may be, applied at a number ofplaces as indicated- `at 16. Theentire num-ber'of cells thus, rig-, idly connected together inseriesconneCtion and constituting the battery are Wrapped. with a'covering 17 of paper or othersuitable insulating material.
